ADS8519IBDBR

Analog To Digital Converters (ADC) Overview

The ADS8519IBDBR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 250 kS/s and features an SPI interface for data communication. The device accepts single-ended input signals and requires an analog supply voltage between 4.75 V and 5.25 V, alongside a digital supply ranging from 1.65 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 93 dB and a signal-to-noise and distortion ratio of 92 dB. Differential nonlinearity is specified at +/- 1 LSB, while integral nonlinearity is +/- 1.5 LSB. Power consumption is rated at 155 mW, with power dissipation at 125 mW. It functions within a temperature range of -40°C to +85°C and is housed in an SSOP-28 package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator eliminates the need for external clocking components.
• Daisy-chainable architecture allows multiple devices to be connected sequentially on a single bus.
• Supports both external and internal reference configurations for flexible system design.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Medical instrumentation such as ultrasound and patient monitoring equipment
• Test and measurement instruments including oscilloscopes and data loggers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm that the SSOP-28 package dimensions align with the target PCB footprint. Ensure the selected variant meets the required operating temperature range for the intended environment. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution is required at speeds up to 250 kS/s. The dual-supply capability allows compatibility with both 5V analog and lower-voltage digital logic domains. Consider the daisy-chain feature if system board space is limited or if multiple converters must share the host microcontroller's serial interface pins efficiently.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8519 family of precision ADCs from Texas Instruments. It shares core architectural similarities with other members like the ADS8519IBDB but differs in packaging and reel configuration. The series is designed for applications demanding high accuracy and moderate speed, positioning it between lower-speed sigma-delta converters and higher-speed pipeline architectures.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8519IBDB serves as the tube-packaged equivalent of this reel-based component. Designers should verify pinout compatibility and electrical specifications remain identical before substitution. No alternative functional replacements are confirmed in the provided documentation.
